Unpaid bookings via COD appearing as processing

It is connected to WooCommerce orders, You can do it by adding custom filter .
Please follow this stackoverflow question. WooCommerce booking plugin using default woocommerce orders for adding booking.
https://stackoverflow.com/questions/53280800/change-cod-default-order-status-to-on-hold-instead-of-processing-in-woocomme

This does not answer the question. What I want is that booking status should sync with the order status so:
1. If booking is set to PAID -> Order status should also change to be Processing
2. If booking is set to unpaid -> Order status should also change to On-Hold
3. If booking is cancelled – > order should also cancel

Cam you please shed some light on how to do it?

It is something that is very essential to the functionality.

Thanks for clarifying, Now we got your point.
As of now we sync order status with Booking, Once order status updated, it will change the booking status as well.
It will not work the other way, that is booking status change have not sync with orders.

We understand it is a necessary feature, and have passed this request to development team. We will be implementing this in future releases

We have released a new version 4.3.0, where we have implemented this feature as an experiment.
By default it will be disabled, You can enable it by adding a filter code in your themes functions.php

add_filter('mvv_booking_sync_order_with_booking',function ($status){
    return true;
},10,1);
